The Week's Core Narrative

1. The Great AI Rotation Intensifies. The semiconductor selloff that began in late June accelerated this week. The SOX index fell into bear market territory while the equal-weighted S&P 500 posted its biggest weekly outperformance versus semiconductor ETFs since May 2009 (MarketWatch, July 17). Chip weakness spread to broader tech: IBM suffered its worst week on record after warning of a shift in client software spending, and Netflix fell over 7% on weak guidance (CNBC, July 17). Yet strategists at EP Wealth, Charles Schwab, and Hightower Advisors all characterized the move as a healthy rotation rather than the start of a deeper selloff: "I don't think the trade is over," said EP Wealth's Adam Phillips.

2. China's Moonshot AI Adds Fuel to the Fire. The launch of Kimi K3 — an open-source model from China's Moonshot AI that the company claims rivals OpenAI and Anthropic — echoed the DeepSeek moment of early 2025, deepening the chip selloff and raising fresh questions about the ROI on US AI infrastructure spending (Barron's, July 17). The launch was curiously timed with President Xi Jinping's first visit to an AI summit in Shanghai.

3. Earnings Season Off to a Strong, Broad Start. Despite the tech weakness, the early macro read from Q2 earnings has been "very strong," per 22V Research. S&P 500 companies are expected to post earnings growth exceeding 20%, a velocity typical of recession recoveries (CNBC, July 17). Travelers surged 9.2% on strong insurance results, helping offset the Dow's decline. Best sector: Energy +1.2%. Worst: Communication Services -2.4%.

4. Consumer and Macro Resilience. Consumer sentiment rebounded to near pre-war levels (Barron's, July 17). Headline CPI eased to 3.5% YoY in June, below the 3.8% consensus, while core CPI cooled to 2.6%. Initial jobless claims fell to 208,000 — the lowest in over two months (IG, July 17).

5. US-Iran Tensions Flare Again. The US military launched strikes targeting Iranian forces after attacks killed two American service members. The escalation appeared to weigh on markets shortly before Friday's close, though strategist Gina Martin Adams noted it's "kind of amazing that stocks are not down more" given the dual headwinds (MarketWatch, July 17).

Macro and Policy Review

Inflation Picture Brightens. US headline CPI eased to 3.5% YoY in June, coming in below the 3.8% consensus, while core CPI cooled to 2.6% against a 2.8% estimate. PPI fell -0.3% month-over-month, reinforcing the disinflation narrative (IG, July 17). The data keeps the Fed's options open, though rate hikes remain on the table as the central bank scales back its public communication.

Labor Market Remains Resilient. Initial jobless claims dropped 8,000 to 208,000 for the week ending July 11, well below the 217,000 expected and the lowest in over two months. Retail sales rose 0.2%, with the control group surging 0.5% following an upwardly revised 0.8% gain in May — suggesting the consumer remains on solid footing (IG, July 17).

Treasury Curve Stabilizes. The US 10-year yield settled around 4.551%, the 2-year at 4.183%, and the 30-year at 5.073% (CNBC, July 16). A firming bond market eased near-term volatility fears for options traders after recent swings. The DXY dollar index held around 100.755.

Global Macro Divergence. China's Q2 GDP moderated to 4.3% YoY, missing the 4.5% consensus, though exports surged 27% and imports jumped 36%. Japan's machinery orders plunged 12.4% month-over-month, much worse than the -4.2% forecast. The UK economy returned to growth in May with GDP rising 0.1% (IG, July 17).

Central Bank Watch. The ECB delivered a 25bp hike at its June meeting to 2.25% — its first since 2023 — but markets expect a hold at Thursday's decision after recent downside inflation surprises. The Bank of Japan is expected to keep rates at 1% at its July meeting, with markets not pricing the next hike until December (IG, July 17).

Equity and Sector Review

Sector Performance. Energy was the standout, gaining 1.2% as WTI crude surged over 4% to $82.47. Communication Services was the worst performer at -2.4%, dragged by Netflix's post-earnings slide. Healthcare, financials, and utilities also posted relative strength, consistent with the rotation theme.

Semiconductor Bear Market. The PHLX Semiconductor Index fell into bear market territory, down 20% from its June 22 peak. The iShares Semiconductor ETF (SOXX) pulled back more than 10% week-to-date (CNBC, July 17). Despite the selloff, BofA analysts argue the move is a valuation reset rather than a fundamental deterioration, and UBS and Barclays remain bullish. Bank of America notes that semiconductor demand fundamentals remain strong, driven by AI infrastructure buildout.

Notable Movers. Travelers surged 9.2% on strong insurance results — the week's best S&P 500 performer. Intuitive Surgical fell 14.2%, the biggest loser. IBM notched its worst week on record after warning of a shift away from software spending. Netflix shares fell over 7% as analysts cut targets on weak guidance (CNBC, July 17). Saab surged over 9% after beating Q2 expectations with a record order backlog of 317.7 billion Swedish crowns (CNBC, July 17).

Breadth and Rotation. The equal-weighted S&P 500 outperformed its cap-weighted sibling by more than a percentage point. The Invesco S&P 500 Equal Weight ETF posted its biggest weekly outperformance versus the iShares Semiconductor ETF since May 2009. 66% of S&P 500 stocks ended the week above their 200-day moving average, near the highest level since late 2024 (MarketWatch, July 17). Small caps continued to outperform: the iShares Russell 2000 ETF is up 19% year-to-date.

European Defense. Saab's blowout quarter highlights the structural demand driving European defense names. CEO Micael Johansson called for a fundamental rethink of European weapons procurement toward long-term industry partnerships. NATO announced plans to order up to 10 GlobalEye spy planes from Saab in a deal potentially worth nearly $5 billion.

Commodities, FX, Credit, and Volatility

Oil Surges on Geopolitical Risk. WTI crude surged 10.73% for the week to approximately $82.47, driven by the resumption of US-Iran hostilities and record US refining margins (Barron's, July 17; IG, July 17). The energy sector was the S&P 500's best performer. Refining margins hit a record, signaling potential upward pressure on gasoline prices heading into late summer.

Gold Pauses. Gold traded around $4,023 per ounce, up modestly on the week but pulling back from recent highs as real yields firmed and the dollar stabilized. Central bank buying and geopolitical tensions continue to provide structural support (Barron's, July 17).

Dollar and FX. The DXY dollar index held around 100.755, marginally lower for the week. EUR/USD was flat at 1.144, GBP/USD at 1.345, and USD/JPY at 162.39 (CNBC, July 16).

Volatility Awakens. The VIX rose 12.19% to 18.77, its highest close in weeks, reflecting the confluence of semiconductor stress and geopolitical escalation. Options traders, however, noted that the firming bond market is easing some near-term vol fears (CNBC, July 17).

Natural Gas and Bitcoin. Natural gas traded at $2.916/MMBtu, up 2.03%. Bitcoin was flat around $64,471 (CNBC, July 16; MarketWatch).

Geopolitics and Event Risk

US-Iran Hostilities Escalate. The US military launched strikes targeting Iranian forces after attacks killed two American service members (CNBC, July 19). The revival of direct conflict weighed on markets ahead of Friday's close and raises weekend gap risk. Oil's surge above $80 reflects the market pricing a geopolitical risk premium.

Trump Speech Targets China. President Trump used a prime-time address to accuse China of extensive 2020 election meddling, alleging illicit acquisition of 220 million US voter files (CNBC, July 17). The accusations could complicate the fragile US-China trade truce ahead of President Xi Jinping's planned September 24 visit to Washington. Separately, Trump's teleprompter operator was suspended over a federal investigation into Kalshi prediction-market bets.

Truth API Launch. Trump Media and Technology Group announced a paid data feed — "Truth API" — providing algorithmic trading firms with "the fastest" access to Trump's Truth Social posts, launching August 1 (CNBC, July 17).
